Debian and RPM packages do not protect config files

The Debian packages for both membase-server and moxi-server do include the configuration files (/opt/membase/etc and /opt/moxi/etc) in the "conffiles" list in the package. This means that dpkg does not treat them as configuration files and replaces them with the new version when upgrading. This destroys the previous config.

If the configuration files were installed under /etc, Debian would automatically handle them appropriately. Alternately, listing the files in the "conffiles" file when building the package should accomplish the same thing.
